Nathan Beyer updated HARMONY-63:
--------------------------------

    Attachment: MessageFormat_patch.txt

Try this patch out. It should resolve the issue and update the test case with a regression test, as proposed by the reporter. It seems like the MessageFormat and other related format classes need some serious testing done, so we may need to just write a full test case to make sure this little fix and others aren't introducing new issues.

>      Project: Harmony
>         Type: Bug
>   Components: Classlib
>     Reporter: tatyana doubtsova
>  Attachments: MessageFormat_patch.txt

> Problem details:
> Method java.text.MessageFormat.parse(String) returns the array of 10 elements when parsing string "1,00,00' using pattern "{0,number,#,####}". It should return array of 1 element.
> Code for reproducing Test.java:
> import java.text.MessageFormat;
> import java.util.Locale;
> public class Test {
>     public static void main(String[] args) {
>         try {
>             MessageFormat mf = new MessageFormat("{0,number,#,####}", Locale.US);
>             Object[] res = mf.parse("1,00,00");
>             System.out.println("result's length: " + res.length);
> 	    for (int i = 0; i < res.length; i++) {
>                 System.out.println("result is: " + res[0]);
>             }
>         } catch (Exception e) {
>             e.printStackTrace();
>         }
>     }
> }
> Steps to Reproduce:
> 1. Build Harmony (check-out on 2006-01-30) j2se subset as described in README.txt.
> 2. Compile Test.java using BEA 1.4 javac
> > javac -d . Test.java
> 3. Run java using compatible VM (J9)
> > java -showversion Test
> Output:
> java version 1.4.2 (subset)
> (c) Copyright 1991, 2005 The Apache Software Foundation or its licensors, as applicable.
> result's length: 10
> result is: 10000
> result is: 10000
> result is: 10000
> result is: 10000
> result is: 10000
> result is: 10000
> result is: 10000
> result is: 10000
> result is: 10000
> result is: 10000
> Output on BEA 1.4.2 to compare with:
> result's length: 1
> result is: 10000
> Suggested junit test case:
> package org.apache.harmony.tests.java.text;
> import java.text.MessageFormat;
> import java.util.Locale;
> import junit.framework.TestCase;
> public class MessageFormatTest extends TestCase {
>     public static void main(String[] args) {
>         junit.textui.TestRunner.run(MessageFormatTest.class);
>    }
>     public void test_parse() {
>         try {
>             MessageFormat mf = new MessageFormat("{0,number,#,####}", Locale.US);
>             Object[] res = mf.parse("1,00,00");
>             assertEquals("Assert 0: incorrect size of parsed data ", 1, res.length);
>         } catch (Exception e) {
> 			fail("Assert 0: Unexpected exception " + e);			
>         }
>     }    
> }
